Eighty milligrams of aprepitant added to a three-drug multimodal prophylaxis strategy can bring benefits to a high-risk population by reducing PONV episodes and rescue antiemetic requirements. This study was registered in the ClinicalTrials.gov (NCT 02357693) database.
OBJECTIVE:The standard therapy for patients with high-level spinal cord injury is long-term mechanical ventilation through a tracheostomy. However, in some cases, this approach results in death or disability. The aim of this study is to highlight the anesthetics and perioperative aspects of patients undergoing insertion of a diaphragmatic pacemaker.METHODS:Five patients with quadriplegia following high cervical traumatic spinal cord injury and ventilator-dependent chronic respiratory failure were implanted with a laparoscopic diaphragmatic pacemaker after preoperative assessments of their phrenic nerve function and diaphragm contractility through transcutaneous nerve stimulation. ClinicalTrials.gov: NCT01385384.RESULTS:The diaphragmatic pacemaker placement was successful in all of the patients. Two patients presented with capnothorax during the perioperative period, which resolved without consequences. After six months, three patients achieved continuous use of the diaphragm pacing system, and one patient could be removed from mechanical ventilation for more than 4 hours per day.CONCLUSIONS:The implantation of a diaphragmatic phrenic system is a new and safe technique with potential to improve the quality of life of patients who are dependent on mechanical ventilation because of spinal cord injuries. Appropriate indication and adequate perioperative care are fundamental to achieving better results.
The use of distal perfusion in descending thoracic and thoracoabdominal aortic surgery remains a controversial issue. Few mainly retrospective studies which directly compare simple clamping with distal perfusion are available. The aim of the present study was such a comparison in an own series of descending and thoracoabdominal aortic replacement. The records of 29 patients who underwent descending or thoracoabdominal aortic replacement between 1988 and 1994 were retrospectively reviewed. Patients were divided into two groups. Group I consisted of 14 patients who received aortic replacement using simple clamping, group II was represented by 15 patients who were operated with distal perfusion techniques. In group II left heart bypass with a centrifugal pump was used in 3 patients, and partial cardiopulmonary bypass with a roller pump in 12 patients. The paraplegia/paraparesis rate was 28.6% in group I and 0.0% in group II (p = 0.0258). There were no statistically significant differences regarding surgical revision for bleeding (14.3% in group I, 14.0% in group II), postoperative renal failure (14.3% in group I 13.3% in group II), postoperative ventilator dependence (9.0 days in group I, 11.2 days in group II), rate of postoperative multisystem organ failure (26.7% in group I, 33.3% in group II), length of stay in the ICU (13.6 days in group I and 13.9 days in group II), and 30-day mortality (21.4% in group I and 33.3% in group II). Methods of distal perfusion in comparison to simple clamping can lead to a lower paraplegia/paraparesis rate in descending and thoracoabdominal aortic surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
